Samsung’s Galaxy S26 series might finally solve the notorious Exynos overheating problem. The upcoming Exynos 2600 processor will reportedly feature revolutionary Heat Pass Block (HPB) technology, bringing PC-grade cooling solutions to smartphones for the first time.

What is HPB Technology?
Heat Pass Block (HPB) acts as a heat sink to reduce chip temperatures more effectively, using a copper-based heat sink that Samsung plans to integrate directly into its new Exynos 2600 processor. The Heat Pass Block adds another layer to the package-on-package structure – a copper heat sink similar to PC cooling solutions.
Samsung’s plan is to place the HPB module on top of the application processor (AP) and DRAM, following the PoP (Package on Package) structure. This innovative approach addresses one of Samsung’s most persistent chip challenges.

How HPB Improves Performance
The integration of HPB technology promises significant performance benefits:
- Higher Clock Speeds: The SoC can reach higher clock speeds and maintain them for longer
- Better Sustained Performance: Better sustained performance during heavy workloads — something Samsung’s in-house chips have struggled with for years
- Reduced Throttling: The presence of the HPB should allow the Exynos 2600 to reach higher frequencies, leading to better single-core and multi-core performance while maintaining its temperatures
Technical Specifications & Timeline
| Feature | Details |
|---|---|
| Technology | Heat Pass Block (HPB) + FOWLP |
| Cooling Type | Copper-based heat sink |
| Manufacturing | 2nm GAA process |
| Expected Launch | Galaxy S26 series (2026) |
| Development Status | Q4 2024 completion target |
Samsung’s Advanced Package (AVP) business unit is developing the technology and aiming to wrap up development by the fourth quarter and begin mass production then.

Why This Matters for Galaxy S26
Exynos chips have historically struggled with thermal management compared to Qualcomm alternatives. Samsung’s Exynos chips are infamous for their worse efficiency and heat management. The HPB technology represents Samsung’s most ambitious attempt to level the playing field.
The rising adoption of on-device AI has also increased concerns about mobile processor overheating. With AI becoming central to smartphone experiences, effective cooling is crucial for the Galaxy S26’s performance.
The Samsung Galaxy S25 established strong foundations, but the S26 series with Exynos 2600 could finally deliver consistent performance. For more details on Samsung’s current flagship lineup, visit Samsung’s official Galaxy page.
